This invention relates to improvements for sockets being more particularly directed to shock absorbing sockets for use in ra dio apparatush i There are in presentvuse several types of shock absorbing sockets, which comprise two sections movable relatively towardsone another, which sections fare interconnected by which to be sure, *form a resilient socket member and its supthe fact that the socket proper in silient relation ber propern 1 It applied thereto.

flexible metallicwmembersx This type of socket requires considerable amount ofexcess material, in particular one insulated meniber is adapted to form the support for the complete socket memberwhich is independent thereof, and whoseonly connection therewith is-by a series of independent members, combine, to collectively port. r l. e

Other types of socket members comprise resilient contacts which receiveztheprongs extendingfrom the vacuum tube but due to which the prongs are held, is fixed to a' panel member; the tube itself is not supported in flexible rewithrespect to the panel memis then, particularlythe purpose of this invention to provide a'simple spring or flexible metallic member'co-operating directly with the socket member, and adapted; to so support it on Fapanel member, whereby the socketmember itself'assumes a resilient relation with respect to the panel, irrespective of theangular direction of the shock or force This is carriedout by providing a single metallic springmember of a particular configuration, whereby parts thereof are directly attachable to the socket member proper, and the remaining portions thereof are attachableto the panelmember, the resilient spring member being so shaped whereby any downward or 'sideward movement, ormovement in any d rection of the socket member proper will causea flexing of the spring andconsejquently provide for a non-jarring and resilient efi'ect upon the'tube being being present in the socket member.

member so bent at its central portionand ofi'set at its end extremities, whereby to provide attaching means at its end extremities to both the'socketmember proper and the panel member, and due to itsparticular angularformationwith respect'tothe respective ends associated with the socket member proper and the panelmember, to respond to any movementin anyplaneby a flexing action due .tothe action of the resilient spring l member, and thus providesfor a shock absorbing efiect upon the socket.

In general, it is aimedto provideYa simple and durable shock absorbing socket capable of simple construction, eflicient tion, and low in production cost.

Specifically it is an object of this invention to provide a resilient socket for use in radio apparatus, wherein the socket proper for receiving the vacuum tube is supported on a= resilient member, whereby movement of the vacuum tube within the socket or a movement of both the socket and the vacuum tube therei in are counteracted and compensated by the flexing of this resilient member.

Still further,it is aimedto provide a novel form of resilient support consisting of,

stamped and bent metal member, portions which are attachable directly to the. socket member, and other portions of whichlare connected to the panel or support, the respective portions attachable to this support being directed in oppositeplanes'an'd oflset'fromone another, and being connected to one another at a point centrallydisposed and integral with the said portions. f

Stilkfurthen it is aimed to provide a novel [resilient support for socket members in applicacapable of being attached tol any form of socket members whatsoever, and serving upon movement to the socket member or tube within the socket member to flex and eliminate any shock whatsoever to the tube with in the. socket. Y

And finally, it aimed to provide a universal type of resilient socket support attachable at some of its end extremitiesto the base of a socket member, and atits other end extremities, to a panelor supporting "member, the respective arms or portions ion thereof being offset from one another and in opposite planes, whereby, an angular movement in any direction provides for a flexing within the resilient supporting member, and a consequent elimination of any shock whatsoeverto the socket or the vacuum tube within the socket.

These and other advantages, capabilities, and features of the invention will appear from the subjoined detail description of one specific embodiment therefor illustrated in the accompanying drawings, in which Figure 1 is a plan elevation oft-he device.

Figure 2 is a side elevation of the device showing the method of attachment to a panel member.

Figure 3 is a side elevation and section along the lines of 33 of Figure 1, indicating the method of attachment to the device of the socket proper.

Figure 4 is an isometric view of the resilient supporting member unattached.

Referring to the drawings in detail, the construction shown comprises an insulating casing 10 forming the supporting base or socket member for a vacuum tube. This base 10 as shown in Figure 3 comprises a hollow body portion formed of a phenolic condensation product and having a head. portion 11 extending upwardly therefrom. lVithin this head portion there is formed by molding a series of apertures 12 into which apertures there is adapted to be rged the pr ngs projecting from the base of the vacuum tube not shown. Adjacent the respective apertures 12 and extending upwardly within the hollow interior 13 of the base member 10 are the spring contact members 1% having bent U-shaped prong contacts 15, which are directly contacted with by a prong being urged from the apertures 12 in the socket member.

These conductors are attached directly to the base member 10 by being bolted to the said base member through members 16 positioned within the cut-out portions 17 formed along the periphery of the end side of the base member 10 adjacent the respective apertures 12. The end extremities 18 of the conductormember 14 haveapertures 19 therein for forming contact with the remaining electrical contacts within the radio circuit.

The central head structure 11 issupported and made rigid at its interior surface by means of a reinforcing rib 20 in the form of a cross having a hub centrally disposed therein through which hub a further connection may be made as desired. Along the outer under periphery of the base there are formed a series of molded hubs 21 in each of which hubs there is adapted the ,pass bolt member 22. It is to these hubs that the resilient shock absorbing member 23 is attached at a plurality of its extremities.

Refe ing o. Figur in a l, t heiil' l be noted that the shock absorbing member 23 comprised of four arms 24, 25, 26, and 27, although it is within the province of the invention to provide for a plurality of arms of varying number, as long as the attachment of the arms to the respective base of thesocket member and the support for the socket member, will bring about a flexing of the same upon the slightest movement of either the socket member or the main panel or support therefor.

It is herein shown that arms 25 and 27 are flexed inwardly from the center 28 of the shock absorbing member 23, the end extremities of the same either being slightly bent outwardly in the opposite direction so that at their points of attachment 29 and 30 as indicated in Figure 3, the end extremities of the said arms are displaced considerably from the said central portion 28. The remaining arms 24. and 26 are bent in the oppositedirection, that is outwardly from the center 28, being displaced inwardly slightly at the end extremities 31 and 32, where the arms are attached to the panel member or supporting base 33, of a radio set by means oii the bolt members 34 and passing through the apertures of the end extremities 31 and 32 of these respective arms.

Since the arms 25 and 27 are disposed in planes opposing each other, but are in the same flat plane at their common center, and also in planes opposing respectively the arms 24 and 26,so that when all the arms are considered together, the multiple resilience or shock absorbing power of the same is imparted upon the movement or actuation of the socket member or the support or panel member to which this resilient member 23 is attached. Thus the co-action'of the arms 24 l and 26 pressing through the common center 28 with respect to the socket memberto which they are attached. and the simultaneous 'coaction of the arms 25 and 2"("through'the common center 28 against the panel support member 33, to which they areattached, will provide a resilient'shock absorbing unit, since thecompletespringstructure 23 includes a series of arms, half of which are oppositely disposed from the other half. and which act in opposite planes to oneanother.

Consequently in this manner it is possible that a movement of the support memberindependent of the socket member, or vice versa, will be compensated by any or all of the respective arms forming the shock absorbing unit and consequently the elimination of any shock or break-age within the-delicate instruments or members on the panel board, or within the socket is, positively provided for. It is obvious that various changes and modifications may be made to the details of construction without departing from thegeneral spirit of the invention; as set forth in'the eapeail eelaiias whereby the socket may be displaced in vary- 1 What I claim is: 1. A resilient supporting member for sup porting vacuum tube sockets comprising a stamped metallic element having a plurality of'arms, extending from a central surface, a socket portion, and a fixed support, alternate arms being otfsetin the same direction and being fixed to the base of a socket portion, and the remaining arms being similarly offset in another direction and attachableto the fixed support, whereby movement of a socket member produces a flexing'of said resilient support member.

2. A shock absorbing element for vacuum tube sockets comprising a socket member, and

a stamped metallic member having a plurality of arms offset from a common central plane, each ofthe arms being offset ina different direction, and adjacent arms being fixed to a socket member and a fixed panel support respectively, whereby movement in any plane of the socket member provides for a flexing of said shock absorbing element.
